Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

This is such a great learning tool for both my 8 and 6 year old daughters! It makes learning and practicing math fun for them. I love that although they are both at different math levels, they both can use this tool and be successful. I am excited to have this over the summer to help them continue to practice their math (and not regress). I see this as something that will grow with them over the years! Great product!!

This is a simple math drilling device / calculator. It consists of 8 levels of each of the following area -- addition, subtraction, multiplication, division, decimals, fractions and percentages. The levels progress rather slowly from simple (1+3) to algebraic thinking (? + 13=42). I like that the multiplication allows you to select the times table that you will be working with. You can use the sound, or not and there is a red light or green light to indicate whether you have reached the correct answer.

It's durable enough for all three of my kids though I doubt it will be around like my old Speak & Math is...they just don't make things like they used to :). It is still a math drill computer so it doesn't make it FUN, per se, but I accidentally read a review before I posted mine and they mentioned keeping it in the car for when they get bored. I LOVE this idea because my two year old has car toys but the older ones don't and this is perfect for them! If you have a math nut, they will love every second of this.

This is going to be perfect during the summer for my 2nd grader who needs to learn his multiplication tables. It will also be useful as he needs to learn division and will help his little sister with addition and subtraction.

I think this is a good compromise between an electronic and flash cards. It's a little more exciting and challenging than using the cards, but not a full-on tablet or game. I like that it's a sturdy and big handheld toy that will be easy to find in all the other toys and games!

My 6-year old loves to "play" with her MathShark to learn math. She sees it as a game rather than a learning tool. Since she's only in kindergarten, we've only worked on addition and subtraction with her, but I can see using MathShark for learning multiplication and division once she's a little older.

Other benefits that I like are that it's great for independent learning because it's self correcting. It's also perfect for car trips because of its portable size.
